Definitions

  • the invention relates to a device for mixing two pasty Masses, which are in particular a dental impression material and a Catalyst mass to accelerate the polymerization of the dental impression material is.
  • the device according to the invention is placed on the two outlet connections Discharge device attached, by means of which by applying pressure the pasty masses are introduced into the mixing device and after Mixing in the mixing device can be output as a mixture.
  • a dynamic mixer is known from EP-A-0 492 412 known.
  • This known device has an essentially tubular one Mixer housing with a mixer shaft rotatably arranged therein.
  • the Mixer shaft has a plurality of radially projecting web-shaped Mixer elements which, when the mixer shaft is driven, for a deflection of the mass flows and thus the two pasty masses mixed together.
  • the pasty masses pass through a radial Front wall at the rear end of the mixer housing into this.
  • the end wall has two inlet connections which are connected to the Outlet nozzle of a device for dispensing the pasty masses be plugged on.
  • the known mixer has a discharge device projecting from the mixer shaft Wiper elements on the inside of the rear end wall move long and pasty material arriving via the inlet connection Transport side. This via the one inlet connector into the interior of the housing pasty material introduced is at least partially in Transports circumferential direction and thus reaches the area of the other Inlet port where, when the dynamic mixer is not driven, back contamination up to the inlet nozzle and further into the this connected outlet port of the associated discharge device can come.
  • the invention has for its object a device for mixing to create two pasty masses, in which the risk of Recontamination is reduced.
  • the invention provides a device for Mixing two pasty masses according to claim 1 proposed.

  • the tubular section of the housing is two in particular provided diametrically opposite radial inlet openings.
  • the at least one Deflection element around a substantially sawtooth-shaped wedge that is bent runs around the axis of the mixer shaft.
  • This deflecting element acts like a screw conveyor in a screw pump and ensures that pasty material directly in the axial direction from the inlet openings is discharged in the direction of the outlet opening. With that Back contamination reliably prevented, because that is always the least a deflection element for the axial transport through the inlet openings in the tubular section of the mixer housing passing pasty masses supported.
  • the deflection element can have a wedge shape.
  • the deflecting element can be used as one to form a helical web extending around the axis; in this exemplary embodiment, the deflecting element thus has the shape of a Thread on.
  • Such rotating webs are from screw pumps and Screw conveyors are known.
  • each deflecting element arranged on the axis, the are expediently arranged diametrically opposite one another.
  • This Deflection elements or each deflection element preferably extends over an angular range of 180 ° to 90 °.
  • the housing has on its rear end on an insert directed transversely to the axis, of which two Protrude inlet connection.
  • the insert is in a conical expanded, adjoining the tubular section Housing section of the mixer and has two channels, which differ from the Extend inlet port from. These two channels are angled radially into a central cylindrical recess on the inside of the Insert part, of which the axis of the mixer shaft with the at least one Deflection element is added. So it forms the cylindrical one Receiving recess of the insert part of a portion of the tubular Housing section of the mixer.
  • mixer elements are located within the tubular housing section between the radial inlet openings and the axial outlet opening several mixer elements, the kind of radial Webs protrude from the axis and close to the inner surface of the tubular Range section.
  • These mixer elements are within several Radial planes projecting from the shaft and lead to a Deflection of the axially extending through the housing Mass flows. This leads to the desired mixing.
  • the Mixing effect is enhanced when these mixer elements due to their radial orientation, the direct current between the Inlet openings and the outlet opening prevent it from going over a larger one Angle range, for example, extend 90 °. This can be realized be that adjacent mixer elements by a rotating Section are interconnected.
  • the mixer shaft has additional flexibility Scraper elements, which due to their flexibility or at least their flexible free ends spaced from the axis Brush along the inside wall of the tubular housing.

All in general it can be said about this dynamic mixer 36 that its Mixer shaft 38 is motor-driven. For this purpose, the Mixer shaft 38 can be coupled to a drive rod 40, which is also by one Motor, not shown, is driven in rotation.
  • the details of the dynamic mixer 36 are particularly based on Fig. 2 clearly.
  • the mixer 36 has a housing 42 which is essentially one cylindrical or tubular section 44 with a flared End section 46 at the rear end facing the extrusion tool 12 48 and has a tapered front end 50.
  • the tapered end 50 is as Exhaust port formed and defines the outlet opening 52 for the Mixture of materials, while at the rear end 48 of the housing 42 two Inlet ports 54,56 are arranged which on the outlet ports 28,30 of Squeezing tool 12 can be plugged.

Starting from the inlet port 54,56 extend through the insert part 62 two channels 64,66, which under Deflection opens in radial openings 68.70. These inlet openings 68.70 are radial with respect to the cylindrical portion 44 of the mixer housing 42 arranged. The two pasty components are in via the channels 64,66 the dynamic mixer 36 transported into, where it is then in radial Impact direction on the mixer shaft 38.
  • the insert part 62 has a central substantially cylindrical receiving recess 69 on the is arranged concentrically to the opening 58 and into which the mixer shaft 38 is inserted.

  • there are four per radial plane Mixer elements 74 are provided, which according to FIG. 2 are close to the inner surface 76 of the cylindrical housing portion 44 range.
  • the mixer element 78 'according to 7 thus has a larger section in a central circumferential section to the inner surface 76 of the cylindrical housing section 44.

  • deflection elements 80 run So in sections helical and ensure an axial Movement component of the pasty mass flows. With this they support Deflection elements 80 the removal of pasty mass, which from the Inlet openings 68,70 penetrates into the cylindrical housing section 44. This supportive and thus reinforcing removal of the pasty masses in axial direction reduces the risk of contamination of the two pasty Masses, i.e. the unwanted mixing or recontamination of the two pasty masses via the inlet openings 68.70 into the channels 64.66 and if necessary continue to the outlet port 28,30. Because if it's in this Contamination and polymerisation, due to the blockage of the outlet port 28, 30, this can be done if necessary residual material still in the tubular bags 20, 22 no longer deliver.
